L The object ofthe invention 1s to adapt the ribbon-guide to type-headsof extraordinary Afortype-writmgr machines of that class known width-as,for instance, those carrying words.

instead of letters-by roviding the guide with yielding sections lbcatedat opposite sides of the type-opening in the lde to depress the activeportion of the rib on and arranged to yieldwhen presented to one of themachine-supporting tracks or 'des in order to permit t e rintmg-point othe machine To the ac complishmentiof this objectithe preferredembodiment of the invention .comi prehends the construction andarrangement .of parts to be hereinafter'described, illustrated in theaccom anying drawings, and defined in the appen ed claims.

. In said drawings, Figure 1 is a sectional ele' vation of a portion ofatype-writing machine accordance with my. invention.l Fig. 2 is asectional plan view of a portion of the machine structure and theribbon-guide. Fig. 3 is a plan view of the ribbon- Fig. 4 is aperspective view of t e guide. Fig. 5 is a detail sectional view ofportions ofi the ribbon-guide'and platen, illustrating the maie yieldsto enable characters to.,be prigiiied close to a track orguide of themachine-supporting frame. Fi 6 is a transverse section onthe line 6 6'ofFglg. 2. Fig. 7 is asimilar view on the line'7 ,7 of Fig. 2, and Fig.Sis a detail perspective view of one ofthe yielding sections of the'guide.

The machine illustrated inthe drawings is the Elliott-Fisherbilling-machine of commerce, disclosed 'more fully in'Patent. No.l

573,868, to R. J. Fisher. This machine insupporting frame '1, mounted totravel longitudmally of a fiat platen 2 for letter-spacing 'deinverted."

u on tracks or guides 3, overlying-the side e es of the platen andconstituting the side ra` s of what 1s known as a machine-supportingframe. Mounted to travel transversely of the platen for letter-spgpingupon the car- Iiage supporting or mac e frame 1 is a carriage v4,equipped with downwardly-acting type-bars 5, one of which is indicatedin Fig. 5. The type-bars are mounted to swing from a type-ring 6,suspended from the casing of the carriage 4l by hangers 7 The ribbonmechanism includes a pair of ,spool-shafts 8 and 9, suitably operatedand supported at o posite'ends of the carriage by hangers 10. he shafts8 and 9 support ribbon-spools 11 and 12, which rotate with. theshaftstofeed the ribbon 13 in one direction or the otheras the carriageis advanced in owhubs 14 of the spools are bearing-thimbles 15,projecting beyond theheads of the spools to rovide,l trunnions, whichare received wit the annular bearing-rings 16 of ribbon-frame-supportingbrackets 17.- The brackets 17 are secured many suitable manner to' thevertically-disposed end portions 18 of the ribbonsupporting and guidingframe 19. The ribbon-guiding frame is designed to lead the ribbon 13under the type-ring and exf tends from one spool to the other. ThisAframe comprises end members 2O of right-angular form, having sideflanges 21 and conj nected by a more or less open intermediate member.or` ribbon-plate 229 lThe ribbon-plate 22 is cut out to' `.form acomparatively Wide central type-opening 23 and parallel ribbon-guides 24and 25, pau-ed at opposite sides of the opening 23, as best shownin'Fig.3.v `The ribbon I3,-passi.1:1g`be'l tween the spools, extendsaroundandunder the ribbon-guiding frame alnd'is threaded over the guiing-fingers 25 and under the ngersv 24. `The`ribbonspools` and theribbon be. s stood in the art, andto facilitatethis move- 'sup ortingand guiding frame are designed to -l llliited laterally in a manner wellunderment' theframe isl provided with guidestuds 26, movable withinguide-loops.27, secured to thejtype-ring 6. cludes in itsl generalorganization' a'carriage- The structure thus lfardescribed.--is` notref,4

more disclosed the idea of bending dow-n the inner-longitudinal edges ofthe guiding-ringers 24-for the purpose of depressing the active portionofthe ribbon-to Wit, that-.portion 'which extends across the type-openingl23 and 1s designed to receive the impactof t e type when the latterdescend to the printin #point -It is with this particular feature Iott econ struction that my present invention is primal rly concerned.

. the ribbonguide is quite wide; This is made' 1 5 It Willbe notedthatthe 23 in 'necessary by' reason of the fact that it is some timesdesirable to equip one jor 'more of the type-bars with anextraordinarily-Wide type'- head carrying several type-facesconstituting a Word which insa'I particular lline of business' is usedwith great ifrequency-for 4instance,

'the Word Wire 'or' nails, used in the ccr'respondence and accounts 'ofconcerns engaged in the manufacture of suchgoods The p'rovision of thiswideI type-opening has been accompanied by a distinct disadvantage, hoW-ever-,for the reasonthat when one 4of the rigidri bbon-depressing langesof the Laganke and' Smith guide is brought into contact with one of thetracks or rails of the machine-supporting frame bythe movement of thecarriage 4 to the right or'left the travel ofthe carriage is arrested,although the printing-point of the machine is severalletter-spacesremoved from the rail. It is therefore impossible to Write close to themargins' of the Work-sheet,

and the right-hand dange constitutes a lineylock 'Which cannot bereleased in order to per- .'mit the printing'of'one or two additionalletters necessary to complete a Word. VTo obviate this difficulty,l Iform the ribbonde pressing flanges separatel from the ribbonplate andvmount them in suchmanner that when a flange contacts vwith one of theside rails or tracks Yof the machine-supporting frame said ilange willyield relative to the ribbon-guide, so that the latter and the car-yriage may continue to moveior the urpose of presenting'theprinting-point of t e machine close to the' rail Vinorder that a' Wordmay be completed or a line of writing 'com menced close to the'r'narginlof the sheet.. As

bestfshown in Fi 4 of-'the dravvings, the

' ribbon-depressing anges ,28 are located at opi positesides ofthetype-opening 23 in the rib. i

v plates 2'9 are sup on-guide and depend fromthe inner ends of shiftable'plates or guide-sections l29.` The orted uponthe ribbon-plate l 22 andare 'pro ded with lon itudinal slots t e ribboneguidin 30 .'for the recetion of heade guide-screws 31, carried by t e ribbon-plate 22.

- To the rear ends of the plates 29 are secured s rings 32, having theirouter ends securedto.A frame and serving to yieldingly retain t e platesin theirgnormal positions With the rib Onjdepressing ilanges l28 thereofheld a ainst the inner'edg-es of the lingers 24. It Wi l now be seenthat normally the depressing-flanges 28 engage" the ribbon at' opposites1des of a comparatively Wide tv e-opening in theribboneguiding frame toho d the active portion of the ribbon closely adjacent to the Writin-surface of the'platen, but'that'vvhen one of t ese flanges is presentedto one of the tracksor 'rails 3, as shown in 1Fig. 5, the movement ofthe carriage Will not be positively arrested,l but may continue the'distance ofone f or more additional letterspaces,
